Abstract
Chest tube insertions (CTI) have a high complication rate, warranting a dedicated Simulation-Based Mastery Learning (SBML) curriculum to acquire technical skills. This randomized controlled trial compares residents' skills in CTI after completing a SBML curriculum with those enrolled in a traditional residency program. Junior residents were baseline tested on cognitive and technical skills (Thiel bodies) before randomization into an intervention and control group. The former deliberately trained CTI on a porcine rib model until passing a predefined pass/fail score and were then summatively tested on Thiel bodies. The latter had no additional training opportunities and was evaluated 3months later. Seventeen residents were recruited and randomized. Following the per-protocol principle, a significant interaction effect for Group×Procedure (F(1,14)=6.2, p=0.026) was observed. Between baseline and summative assessment, both the control group (28.0±8.2 vs. 43.6±8.1, p<0.001) and the intervention group (33.2±7.7 vs. 57.6±5.7, p<0.001) significantly increased their scores. The intervention group outperformed the control group at summative assessment (43.6±8.1 vs. 57.6±5.7, p<0.001). All participants in the intervention group and one resident in the control group achieved the pass/fail score. This SBML curriculum enabled quicker and superior skill acquisition. Skills trained on a porcine model are transferred to the highly realistic Thiel bodies and reach expert level, potentially increasing resident skill in clinical practice.
